I've just follwed the link I just gave out, and found that synaescope
has had a new release with a few bug fixes and a few nice looking
improvements. I'm probably not going to have time to port this in the
near future, so if anyone else wants too ...
I suspect re-doing the port from scratch is the best plan.
(I'd be happy to answer questions about how to write scopes - need to
put that kind of thing in the documentation too.)
